| 摘 要： | 将阳离子表面活性剂CTAB引入钛阳极氧化物涂层制备体系,采用热分解方法在TA2基材上制备出RuO230%-TiO270%涂层.通过XRD分析了涂层电极的组织结构,采用极化曲线方法评定电极的电催化性能,用强化测试方法研究了电极的稳定性.结果表明,引入活性剂在细化电极涂层的晶粒度上有显著作用,晶粒的细化有助于提高涂层真实比表面积,从而提高电极的电催化活性.加入适量CTAB能提高电极稳定性,而过量的CTAB则会助长锐钛矿相TiO2生成,使电极的稳定性明显下降.由此可知,要提高电催化活性并提高其耐腐蚀性能,可以通过控制CTAB加入量来实现.

| Abstract: | RuO230%-TiO270% coated anodes were prepared by thermal decomposition method onto pure titanium TA2 substrates while the cationic surfactant cetyltrimethylammonium bromide(CTAB) was introduced into this process.XRD and electrochemical testing methods were applied to investigate the effects of the cationic surfactant CTAB on the structures and properties of Ru-Ti oxide anodes.The results showed that the introduction of surfactant in precursors has an important influence on grain refinement.Excessive surfactan... |
